Dell Inc reports that sales to large corporate customers were up 27 per cent in the same quarter, while public sector revenue was up 20 per cent and sales to medium-sized businesses were up 24 per cent.

Around 80 per cent of Dell's overall sales come from business customers, with many now refreshing old PCs and servers as they emerge from the recessionary cost-cutting and belt-tightening of the last few years.

As such, Dell's desktop PC sales were up 21 per cent and server sales were up 20 per cent.

CEO Michael Dell said in a statement: "Dell is growing in the right areas, and I'm very excited about our momentum."

Dell reaffirmed its forecast for full-year revenue growth of 14 per cent to 19 per cent.
